Hookes Law SC1

Do Elastic bands follow Hookes Law?

Aim: To investigate elastic bands, whether they follow Hookes Law.

Equipment: Stand, boss, G Clamp, Elastic band, ruler, weights

Diagram:

Method:

  • I will setup my equipment as I have shown in my diagram.
  • I am going to do 3 experiments using different elastic bands. In the 1st experiment I will add masses in small amounts.
  • On the 2nd experiment, I will keep loading weights until near breaking point.

Middle

  • Once I have all my results I will then take the weights off 1 by 1 to see if the elastic band returns to its original form. I will only do this for the 1st and 2nd experiment.

Safety:  

  • I will have to wear goggles so when the elastic band snaps it won’t flick in my eye.
  • I will use a G Clamp so the equipment won’t fall.
  • I won’t put my feet under the table as the weights might fall.

Fair Test:

I will make this a fair test by:

  • I will make the results accurate.
  • I will use the same equipment.
  • I will keep the ruler at the same height

Prediction:

First Experiment:

Conclusion

Evaluation:

My results were reliable, but to get my results more accurate I would like to repeat the experiment, my rules was moving too much, so I think I could have had another person to hold the ruler, this would prevent the ruler from moving about, and would make my results more accurate.

I did get some unusual results on my graphs, but I am not sure what caused them, I feel it was to do with my inaccurate results. For improvements I would repeat the experiment, and I would take more time over it, especially when I measured with a ruler. I feel overall I have had really good results but for the best results I would need more time so I could get more accurate results.

Here's what a teacher thought of this essay

3 star(s)

Overall a 3 star piece of work. The practical procedure should yield some valid data. It is a method that could be followed by other people. The conclusion could be improved and expanded on. There needs to be some explanation of the results achieved. Why did this happen when this was done? Link it in to the science.

    The length of the stretched object should be proportional to the force applied to it. For the graph we can see that the gradient is not straight. There for we can almost immediately tell from our results that this rubber band might not apply to Hooke's Law Evaluation; To have

    the amount of paper cups increase the terminal velocity is faster, the shorter time it takes for it to hit the ground. So then the more paper cake cases that were dropped the faster its terminal velocity. At the instant of release there is no friction because the object is not moving.

  1. Investigate how the weight of an object affects the force required to overcome friction.

    I also predicted that the static and dynamic friction would be directly proportional to the weight of the object pressing down onto the surface. This has also been proven true as nearly all of my points, except for a few that are probably anomalous results anyway and which I

  1. The Physics of Paper Helicopters

    I intend to do this by attaching paperclips to the body of the helicopter. Each paperclip that I will use weighs 1.41 grams, and the mass of the helicopter without any extra mass on it is 4.92 grams. I will keep the height of 6m constant throughout the experiment, and use the same helicopter throughout the experiment.

  2. Determining the acceleration due to gravity by using simple pendulum.

    I have planned to measure distance greater than 1m but measuring them was a problem as we only had access to meter ruler. To overcome this problem I had to take length less than 1m. - The retort stand would not stay stiff which caused some time as I had find some heavy mass objects to support the retort stand.
